In the Seattle area, where I work, we get a lot of rain. From the mid-90s to the mid-2000s, there were many high-profile cases of water damage caused by improperly detailed siding, mostly on condos and other multifamily housing.

Grace Ice & Water Shield HT provides the same protection against ice dams and wind-driven rain as the company's standard underlayment - but it's made with an adhesive that is unaffected by temperatures as high as 240°F, the maker says.
